A spear gun is an underwater weapon that fires a harpoon. It is seen and used in the films Thunderball, The Spy Who Loved Me, For Your Eyes Only, Licence to Kill, Tomorrow Never Dies, and the unofficial Never Say Never Again.
In the 1965 film Thunderball, spearguns are used by James Bond, Emilio Largo's men, the U.S. coast Guard Frogmen, and Domino Derval. Bond used one to kill Largo's henchman, Vargas. In the underwater battle, both the Coast Guard and Largo's men used the spearguns to fight each other. On the Disco Volante, before Largo kills Bond with a pistol, Domino kills Largo with a speargun to avenge her brother.
In The Spy Who Loved Me, Bond manages to get away from the Liparus crew by killing two guards with a speargun found on top of a cart filled with tanks.
